Hi

I need to get some 3/6" x 6" bolts and I am told they are 'UNC', whatever
that means. Does anyone have a source for US size bolts?

Wash your bloody mouth out son! UNC - Unified National Coarse - British
through
and through. Nothing to do with yanks. You mean 3/8" I presume not 3/6".
Go to
a nut and bolt stockist same as all the other bolt queries this group
seems to
produce.



Unless I am mistaken, the differences between UNC and Whitworth are very
slight - the TPI is the same but the threadform is slightly different - but
for most purposes they are interchangeable.

Your original bolts may even be Whitworth - it isn't that easy to tell the
difference.
